Does Your Organization Have a Security.txt File? (Krebs on Security)

Actualités, Sécurité
It happens all the time: Organizations get hacked because there isn’t an obvious way for security researchers to let them know about security vulnerabilities or data leaks. Or maybe it isn’t entirely clear who should get the report when remote access to an organization’s internal network is being sold in the cybercrime underground. In a bid to minimize these scenarios, a growing number of major companies are adopting “Security.txt,” a proposed new Internet standard that helps organizations describe their vulnerability disclosure practices and preferences. An example of a security.txt file. Image: Securitytxt.org. The idea behind Security.txt is straightforward: The organization places a file called security.txt in a predictable place — such as example.com/security.txt, or example.com/.well-known/security.txt. What’s in the security.txt file varies somewhat, but most include links to information about the…

Microsoft Patch Tuesday, September 2021 Edition (Krebs on Security)

Actualités, Sécurité
Microsoft today pushed software updates to plug dozens of security holes in Windows and related products, including a vulnerability that is already being exploited in active attacks. Also, Apple has issued an emergency update to fix a flaw that’s reportedly been abused to install spyware on iOS products, and Google‘s got a new version of Chrome that tackles two zero-day flaws. Finally, Adobe has released critical security updates for Acrobat, Reader and a slew of other software. Four of the flaws fixed in this patch batch earned Microsoft’s most-dire “critical” rating, meaning they could be exploited by miscreants or malware to remotely compromise a Windows PC with little or no help from the user. Top of the critical heap is CVE-2021-40444, which affects the “MSHTML” component of Internet Explorer (IE) on Windows 10 and…

KrebsOnSecurity Hit By Huge New IoT Botnet “Meris” (Krebs on Security)

Sécurité
On Thursday evening, KrebsOnSecurity was the subject of a rather massive (and mercifully brief) distributed denial-of-service (DDoS) attack. The assault came from “Meris,” the same new “Internet of Things” (IoT) botnet behind record-shattering attacks against Russian search giant Yandex this week and internet infrastructure firm Cloudflare earlier this summer. Cloudflare recently wrote about its attack, which clocked in at 17.2 million bogus requests-per-second. To put that in perspective, Cloudflare serves over 25 million HTTP requests per second on average. In its Aug. 19 writeup, Cloudflare neglected to assign a name to the botnet behind the attack. But on Thursday DDoS protection firm Qrator Labs identified the culprit — “Meris” — a new IoT monster that first emerged at the end of June 2021. Qrator says Meris has launched even bigger…

Gift Card Gang Extracts Cash From 100k Inboxes Daily (Krebs on Security)

Sécurité
Some of the most successful and lucrative online scams employ a “low-and-slow” approach — avoiding detection or interference from researchers and law enforcement agencies by stealing small bits of cash from many people over an extended period. Here’s the story of a cybercrime group that compromises up to 100,000 email inboxes per day, and apparently does little else with this access except siphon gift card and customer loyalty program data that can be resold online.
